How about using a watergun with chloride...
If your outnumbered, just wandering:P

Chloride? as near as I can recall thats just a simple harmless salt. Chlorine? Much more potent. More so if you get the stuff used to treat spa's and pools as opposed to simple bleach. HOWEVER,,,,should you use such a weapon you almost certainly be prosecuted and sued. Why bother with improvised stuff when there are so many purpose built tools of the trade? Are you a minor? skip it all and deal with things through your parents and the authorities. (as well as fighting the best you can) If you are an adult I would recomend that you model your weapons and use of force model after a police department. After all, they have already field tested and litigated everything that they use. K-

Watergun, why not just throw dirt in their eyes that will work just as well. I seriously doubt you are going to carry a watergun full of clorine wherever you go, stick with more realistic thinking.

geez. while your going on the subject of a watergun filled with a dangerous chemical. why not just go all out and have concentrated hydrogen peroxide?
idiot...

The best weapon of all in my opinion is AVOIDANCE. I cant stress that enough. Reasonable people just dont go there. Unreasonable people do and oftentimes dont make it out.

dorks

bazookahs and tanks and missiles...

hand weapon = pen (tis mightier then the sword.) You can write nasty letters to someone, and even spray ink with it.

in order to have cloride, clorine has to be bonded with something. sodium cloride for example. and a water gun filled with clorine wont help much because in it's pure form, clorine is a gas.

Particularly good if you live in a country/state that does not allow you to legaly carry weapons :jif lemon juice in the squeezy lemon container.

lol! if you are talking about chlorine gun, i would recommend acid and even base guns. sulphuric acid? sodium hydroxide? even more potent
